I have already used the data sheet from Amtel's site to troubleshoot the chip (ab initio) and found no response to v/ma measurements. As for "how?" I was using the power supply that came with the radio and suppose it tasted a power surge. When I did open the unit I shocked to find no fuse ...

Yes, I had considered RF shielding kind of subconsciously regardless of the circuit design. What would you suggest if I wanted to install a band selection range (toggle switch)? Do you think there is any greater level of sensitivity and accuracy if the meter is composed of seperate sub-circuits, or ...

I became the victim of bad circuit design, I cooked this IC (U2510B) about 2 years ago. It is the receiver and audio amp for a Baygen Free play radio. You would think that for a $150 radio (maybe $20 at a junk sale) they could put a fuse in the power supply. Anyone have experience with this chip or ...

Thanks for the input Ed! I just got involved in Amateur Radio about a year ago, and finally broke down and took technician class exam. I am a physicist by training, and have not fooled around with practical electronics for years. Your advice is greatly appreciated!!

Rather that spend time trying to build one, I am making a decision to purchase a RF field strength meter. Does any one have experience with MFJ-801? <p>http://206.131.241.58/ubbcgi/ultimatebb ... wtopic&f=1

I am certainly not a pro on any of the latest S-band technology. But looking at the fundamentals, Radiation acts more like light the higher the frequency (more directional and line-of-sight). Therefore you could be getting lots of RF reflection based on the immediate enviroment (your 10 acres).

Any one have some advice on building field strength meter? Perhaps a frequency range of 100MHz to 2.5 GHz.
